Historical Zoning Ordinances

The Zoning Ordinances below appear as adopted in the year
indicated. However, each Zoning Ordinance had multiple amendments between
the year of adoption and the next adopted Zoning Ordinance in the series.
In addition, there may be related provisions contained in other
regulatory documents, such as the Building Code or the Subdivision
Ordinance, that apply but are outside the purview of the Department of
Planning and Zoning. To determine which Zoning Ordinance provisions were
in effect at a particular time, contact the Zoning Administration
Division at 703-324-1314.

For the convenience of the public, historical Zoning Ordinances are
available for review in portable document format (PDF). In order to view
the documents, you will need to have the free Adobe
Reader Version 6.0 or higher installed on your computer.

The current Zoning Ordinance in effect was adopted by the Board of
Supervisors on August 14, 1978, and may be viewed on our main Zoning Ordinance page.
